Wool - raw material of nature



Structure of wool fibres
Wool is a protein fibre (ceratin) and consists of amino acid which is also the basic content of human bodies.

Characteristics of wool

  • It absorbs 40% water at 100% humidity without feeling wet (e.g. good absorption of perspiration)

  • Hydrophobic and hydrophilic attributes

  • Highest absorbency in comparison to other fibres

  • Flame resistant, does not melt

  • Ignition point at 600°C

  • Biodegradable, light, soil-resisting

  • Renewable raw material


Definition of woolfelt
DIN standard 61 205 (Deutsche Industrie Norm 61 205) defines felt as a textile structure which is created by the wet felting process where the inherent nature of wool and other animal hairs is utilised by pressure and warm moisture.

In the past, one called “felting” only the process where carded wool was doused with warm suds to form the cloth. Today “felting” means the complete manufacturing process from the fibre opening to the final treatment.
